This is coolbert:
Here from the Russian Internet media outlet RT [Russian Times] the type of item that from back in the days of the old Soviet Union would have been TOP SECRET!
Weapons depot explosion non-nuclear. But having the explosive power of a tactical atomic weapon. The Big Boom!
"WATCH jaw-dropping moment of ‘nuke-like’ explosion at Siberian ammo depot"
"Powerful explosions which devastated an ammunition depot in Russia’s Krasnoyarsk region produced massive blast waves across the cloudy skies, with the moment of the biggest explosion caught on video by a local resident."
"The footage, filmed not far from the town of Achinsk, shows two massive blasts. One of them produced a massive mushroom-like plume of black smoke, which rose up from behind a forest. The second one was accompanied by a burst of sparkles, which look like fireworks but are actually a high-caliber tank and artillery shells flying through the air and burning as they go."
My thoughts instantaneous to include: 1. This was tit-for-tat retaliation by the Ukrainians. Two Ukrainians weapons depots thought to have sabotaged in the the last few years by drone attack. Read here and here of these incidents. 2. A Soviet naval depot detonation  the explosive force when detected have thought to have been an ATOMIC DETONATION!
Munitions intuitively understood as inherently dangerous. You want them to go off only when you want them to go off! Otherwise, stand clear!
